Hi There,

Please help!

I am planning to set-up a T1 Inter-Cluster Trunk IP telephony lab.

Is it possible to make a Cisco 2821 router with 3 VWIC-2MFT-T1 as hub or simulated PSTN and Cisco 2801 w/ VWIC-1MFT-T1 as spokes or simulated T1 customers?

I have seen a this kind of configuration in CIPT-1 Course lab topology but instead of using a Cisco 2821 router as hub, CIPT-1 uses WS-6608-T1 voice services module. This configuration was used for Inter-Cluster voice communication.

When the card is set up to use ISDN PRI signaling, ISDN data connection is not supported. The card is unable to terminate the ISDN 64 K or 56 K data connection. It supports only voice-call termination when using ISDN PRI signaling.

Also, the Multi-Flex Trunk, with or without the accompanying voice-enabling hardware, is unable to terminate a modem connection on the router in a traditional Network Access Server (NAS) dial scenario.

Hey negrevi

Are you wanting to build a PSTN switch?

If so, then I would assume that logically it cannot be the hub. It's like Cisco FR switch scenario - agree?
